초록
Ethylacetoacetate로부터 2단계의 연속합성을 통하여 생성되는 5-methyl-4-imidazolecarboxylic acid ester의 합성반응 속도론과 중간 생성물인
The chemistry of 5-methyl-4-imidazolecarboxylic acid ester synthesis involves three distinct reaction steps. Of these the rate of formation of diketone was found to be a function of oxime and HCl concentration and temperature by the batch experiment. The decomposition of diketone was found to be a slow process whereas temperature was the only variable to affect it significantly. An empirical rate expression for the net formation of diketone fits the experminetal data satisfactorily. The principal objectives of this study are to study the kinetics of the diketone formation reaction and to develop the empirical rate expression.
